来自印度尼西亚爪哇岛 Cikalong 的真实巨齿鲨（Carcharocles megalodon）牙齿

高品质巨齿鲨牙，尖端完好、锯齿和釉质完好，

巨齿鲨（Megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是已灭绝的鲭鲨科鲸齿目的一种，约生活在2300万年至360万年前（始新世早期至上新世期间）。它曾被认为属于 Lamnidae 家族，是大白鲨（Carcharodon carcharias）的近亲；但现今被归入灭绝的 Otodontidae 家族，与大白鲨在早白垩纪分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以零星遗骸为人所知，其外形与最大体长尚不确定。科学家对其外观到底更像大白鲨的更矮壮版本、鲸鲨（Rhincodon typus）、抚鲨（basking shark，Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最新且误差范围最小的估计表明其最大长度可达20.3米（67英尺），体重可达103公吨（114短吨）。

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good  tip, serrations and enamel, 

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.

While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) or the sand tiger shark (Carcharias taurus). The most recent estimate with the least error range suggests a maximum length estimate up to 20.3 meters (67 ft),  weighs up to 103 metric tons (114 short tons)
